As shown in fig. 1 and 2, based on the existing structure of a suspended magnetic suspension train, the invention provides a suspended magnetic suspension track space structural member data acquisition system, which is mainly used for acquiring and processing data of the space posture of an inverted U-shaped track beam 11 and the distance between permanent magnetic suspension tracks 14 on two sides during construction to judge whether the space posture reaches the standard or not.
The data acquisition system specifically comprises a carrier 10 which is arranged at the bottom end of an inverted U-shaped track beam 11 and can move along the direction of a permanent magnetic suspension track 14 in the inverted U-shaped track beam 11, wherein an infrared distance measurement data acquisition module for measuring the distance between the permanent magnetic suspension tracks 14 on two sides in the inverted U-shaped track beam 11, a height data acquisition module for measuring the vertical heights of different positions of the inverted U-shaped track beam 11, a displacement data acquisition module for generating displacement by the motion of a carrier 101 and a data processing module are arranged on the carrier 10; the data collected by the infrared distance measurement data collection module, the height data collection module and the displacement data collection module are transmitted to the data processing module.
Wherein, infrared range finding data acquisition module specifically is infrared range finding sensor 3.
Through the system, the standard reaching judgment of the space structural member of the magnetic suspension track is realized, and the judgment method can be summarized as follows: respectively collecting vertical height values of different positions of an inverted U-shaped track beam 11, horizontal displacement values of displacement generated by movement of a carrier 10 and horizontal distance values between permanent magnet suspension tracks 14 on two sides in the inverted U-shaped track beam 11, then calculating a gradient value of the permanent magnet suspension tracks 14 according to the vertical height values and the horizontal displacement values, finally judging whether the horizontal distance values and the gradient value are within a preset threshold range, and if any one of the horizontal distance values and the gradient value does not meet the threshold range, judging that the permanent magnet suspension tracks do not reach the standard. The specific method comprises the following steps:
the initial position of measurement is selected on the permanent magnet suspension track 14 as a reference point, and the vertical height value h, the horizontal displacement value X and the horizontal distance value d between the permanent magnet suspension tracks 14 on the two sides in the inverted U-shaped track beam 11 are measured through a height data acquisition module, a displacement data acquisition module and an infrared distance measurement data acquisition module respectively.
And moving the carrier 10, and selecting different time points for measurement again, wherein the time points can be selected from a plurality of time points, and the selection mode can be equal intervals or unequal intervals. The following is a detailed description of two time points as examples:
as shown in FIG. 4, the reference point is set at time t1, and the re-measurement time is t2, where the vertical height values are ht1And ht2The horizontal displacement values are respectively Xt1And Xt2And the threshold range of the gradient value of the inverted U-shaped track beam 11 of the system is set as follows: [ f ] ofmix，fmax]，fmaxAt maximum gradient, fmixIs the minimum slope.
the slope value f from t1 to t2 is calculated as: f ═ ht1-ht2)/x1-x2。
When f is within the threshold range, the gradient of the inverted U-shaped track beam 11 reaches the standard, otherwise, the gradient does not reach the standard.
The measurement of the horizontal distance value d is based on the specific construction implementation of the carrier 101:
the carrier 10 comprises a horizontal fixed shaft 1 which is arranged at the bottom end of an inverted U-shaped track beam 11 in parallel, a telescopic sliding rod 2 is vertically arranged on the horizontal fixed shaft 1, two sides of the top end of the telescopic sliding rod 2 are respectively provided with an infrared distance measurement data acquisition module, namely an infrared distance measurement sensor 3, the infrared distance measurement sensors 3 are uniformly used below, the positions of the infrared distance measurement data acquisition modules are right opposite to the permanent magnetic suspension track 14, and a height data acquisition module and a displacement data acquisition module are arranged on the horizontal fixed shaft 1.
As shown in fig. 3, D1 and D2 respectively indicate the distances measured by the infrared distance measuring sensors 3 on the left and right sides from the permanent magnetic levitation tracks 14.
Each infrared distance measuring sensor 3 has a pair of infrared signal transmitting and receiving diodes, the transmitting tube transmits an infrared signal of a specific frequency, the receiving tube receives the infrared signal of such a frequency, and when the infrared detection direction meets an obstacle, the infrared signal is reflected back to be received by the receiving tube.
And 3, measuring the distance d as tv/2, wherein t is the time taken for the infrared signal to be emitted and reflected back, and v is the speed of the infrared signal propagating in the air.
Therefore, d1 is (t11+ t12) v/2, and d2 is (t21+ t22) v/2;
wherein t11 is the time from the signal transmission of the left infrared distance measuring sensor 3 to the obstacle (here, the permanent magnetic suspension track 14); t12 is the time when the infrared signal emitted from the left infrared ranging sensor 31 is reflected back to the receiving tube from encountering an obstacle;
t21 is the time from when the right infrared ranging sensor 3 transmits a signal to when it meets an obstacle, and t22 is the time from when the infrared signal transmitted from the right infrared ranging sensor 3 is reflected back to the receiving pipe from when it meets an obstacle.
D is d1+ dr + d2, dr being a fixed value, in particular the distance between the two infrared distance measuring sensors 3. Setting a permissible minimum distance D between permanent magnetic levitation tracks 14mixAnd an allowable maximum distance D between the permanent magnetic suspension tracks 14maxWhen the distance D between certain points actually measured by the permanent magnetic suspension track 14 is smaller than DmixOr greater than DmaxTime indicates that the track pitch is unsatisfactory.
According to the above measuring method and calculating method for three data values, the initial position is selected as the reference position, the data information is set to (h 0x 0d dr), and the carrier 101 is pushed in the track direction, so that the vertical height difference, the horizontal displacement difference, and the horizontal distance difference can be directly measured.
The vertical height sensor and the infrared distance measuring sensor 3 fixed on the carrier 10 automatically and continuously collect data, the collection frequency can be set as required, and the collected data is processed by the data processing module 400.
The data processing module comprises a central processing unit for receiving acquired data, a wireless sending module connected with the central processing unit, a wireless receiving module arranged at a remote terminal, a PC (personal computer) and a data display module; the central processing unit and the wireless transmitting module are arranged on the horizontal fixed shaft 1, the wireless transmitting module transmits data processed by the central data processing unit to a wireless receiving module of a remote terminal, and the data is received by a PC (personal computer) and is displayed in forms of tables and graphs through the data display module after being processed, and one display mode is shown in figure 5.
In the process of moving the carrier 101, the horizontal fixed shaft 11 may be deviated left and right or up and down, so that the measuring component and the permanent magnetic suspension track 14 are not vertically measured as before, and thus an error is easily caused to exist, and in consideration of this privacy, the embodiment provides a solution, specifically, a self-adjusting component is arranged at the top end of the telescopic sliding rod 2 for adjusting and maintaining the perpendicularity between the laser pulse emitted by the infrared ranging data acquisition module and the permanent magnetic suspension track 14, the self-adjusting component comprises a linkage shaft inserted into the top end of the telescopic sliding rod 2 and an omnidirectional pan/tilt head connected with the linkage shaft and located at the top end of the telescopic sliding rod 2, and the two infrared ranging data acquisition modules are mounted on the omnidirectional pan/tilt head; the omnibearing tripod head is provided with a laser pulse for measuring an infrared distance measurement data acquisition module and a direct measurement system whether vertical between the permanent magnetic suspension tracks 14, wherein the direct measurement system comprises an infrared emitter which is arranged at a relatively fixed position with the infrared distance measurement data acquisition module (an infrared distance measurement sensor 3) and a CCD detection element for detecting infrared rays.
The angle value between the infrared distance measuring sensor 3 and the infrared emitter which are relatively and fixedly arranged is fixed, so that the laser spot distance of the laser pulse on the permanent magnetic suspension track 14 is basically unchanged, and if the infrared distance measuring sensor 3 is inclined, the laser pulse of the infrared distance measuring sensor 3 is not in a direct vertical measuring distance with the surface of the permanent magnetic suspension track 14, so that the distance measurement of the two permanent magnetic suspension tracks 14 is not accurate finally.
When the situation occurs, the laser spot distance between the infrared distance measuring sensor 3 and the infrared emitter on the permanent magnetic suspension track 14 is obtained through the CCD detection element and is transmitted to the central processing unit for analysis and processing, the central processing unit judges whether the laser spot distance is the same as a set value, and when a certain deviation value occurs, the central processing unit controls the omnibearing pan-tilt to adjust the angle of the infrared distance measuring sensor 3, so that the vertical measurement is continuously kept.
